public class Matrix
extends AbstractXJdfType<String,Matrix>

Coordinate transformation matrices are widely used throughout the whole printing Process, especially in Layout Resources. They represent two dimensional transformations as defined by [PS] and [PDF1.6]. For more information, refer to the respective reference manuals, and look for “Coordinate Systems and Transformations.” The “identity matrix”, which is “1 0 0 1 0 0”, is often used as a default throughout this specification. When another matrix is factored against a matrix with the identity matrix value, the result is that the original matrix remains unchanged. Coordinate transformation matrices are primitive data types and are encoded as a list of six numbers (as doubles), separated by whitespace: “a b c d Tx Ty”. The variables Tx and Ty describe distances and are defined in points.
